Has your insurer just notified you of a denial of compensation following a claim? This rejection may seem final, but there are solutions to challenge it. In France, insurers are obligated to justify their decisions and comply with strict regulations. However, many policyholders abandon their claims due to a lack of awareness of their rights. This guide explains step-by-step how to respond, what arguments to present, and what remedies to pursue to assert your rights.

Why Might Your Insurer Refuse to Compensate You?

Before considering a challenge, it is essential to understand the common reasons for denial. Insurers typically rely on contractual clauses or factual elements to justify their decision. Here are the most frequent reasons:

1. Non-Compliance with Contractual Obligations

Your insurance contract imposes obligations, such as reporting a claim within specified deadlines or providing precise evidence. If you fail to comply, the insurer may legitimately refuse to cover the claim. For example:

  • Missed reporting deadline: Most contracts require a report within 5 days (sometimes 2 for theft). A delay may result in denial.
  • Omission or misrepresentation: If you omitted to mention a material fact during the application (such as a prior claim), the insurer may invoke the nullity of the contract.
  • Failure to comply with security measures: For theft, if you did not activate the alarm as required by the contract, compensation may be denied.

2. Exclusions of Coverage

All contracts include exclusions, i.e., situations not covered. For example:

  • Damage caused by an unidentified third party: If your car is vandalised and the perpetrator is not found, your insurer may refuse to cover the repairs.
  • Intentional loss: If the insurer believes you caused the loss (e.g., arson), they will not compensate you.
  • Normal wear and tear: Damage due to the natural ageing of an item (such as an old roof) is generally not covered.

3. Disagreement on the Assessment of the Loss

The insurer may dispute the amount of damage you are claiming. For example:

  • Underestimation of repairs: If the expert appointed by the insurer estimates that repairs cost less than you claim.
  • Value of the item: In cases of theft or total destruction, the insurer may dispute the declared value of the item (especially if it is old).

4. No Coverage for the Claim

Some contracts do not cover all types of claims. For example:

  • Natural disasters: If your contract does not explicitly mention this coverage, the insurer may refuse to compensate you after a flood.
  • Non-material damage: Some contracts exclude non-material losses (such as stress or loss of income).

Steps to Challenge a Denial of Compensation

If you believe your insurer’s refusal is unjustified, here is the procedure to challenge it, step by step.

1. Review Your Contract Carefully

First, check the clauses of your contract to understand:

  • The coverages subscribed (what is covered and what is not).
  • The exclusions of coverage.
  • The obligations incumbent upon you (reporting deadlines, prevention measures, etc.).

This step will allow you to verify whether the refusal is justified or not. If the contract is unclear or ambiguous, this may work in your favour.

2. Request a Written Explanation from Your Insurer

Under French law, the insurer is obligated to provide a written justification for their refusal. If this has not already been done, request a detailed denial letter explaining:

  • The precise reasons for the refusal (contractual clauses invoked, factual elements).
  • The possible remedies to challenge this decision.

This letter will serve as the basis for preparing your challenge.

3. Respond in Writing with Your Arguments

Once you have identified the points of disagreement, draft a challenge letter addressed to your insurer. Here is how to structure your response:

a. Summary of the Facts

Briefly describe the claim (date, circumstances, damage suffered) and mention the date of your initial report.

b. Refutation of the Reasons for Denial

For each reason invoked by the insurer, provide counter-arguments supported by evidence:

  • If the denial is based on a reporting deadline: Show that you complied with the deadlines (copy of your report submission, acknowledgment of receipt).
  • If the denial concerns an exclusion of coverage: Demonstrate that the claim falls within the scope of the subscribed coverages (precise quotations from the contract).
  • If the denial relates to the assessment of the loss: Attach quotes or contradictory expert reports to prove the actual amount of the damage.

c. Request for Re-examination

Conclude your letter by asking the insurer to re-examine your file in light of your arguments. Set a reasonable deadline (15 to 30 days) to receive a response.

d. Sending the Letter

Send your challenge by registered post with acknowledgment of receipt to retain proof of your action. Keep a copy of the letter and any attachments.

4. Engage an Independent Expert

If the insurer maintains their refusal after your challenge, you may engage an independent expert to assess the damage. This contradictory expertise can serve as evidence to contest the insurer’s assessment.

  • How to choose an expert?: Prefer an expert listed on an official register (such as the list of judicial experts) or recommended by a consumer association.
  • Cost: The fees of an independent expert are at your expense, but you may include them in your compensation claim if you succeed.

5. Refer the Matter to the Insurance Mediator

If your insurer still refuses to compensate you after your challenge, you may refer the matter to the Insurance Mediator. This free and independent service aims to find an amicable solution between you and your insurer.

a. Conditions for Referring to the Mediator

  • You must have exhausted internal remedies with your insurer (written challenge without result).
  • The dispute must concern an insurance contract taken out in France.
  • The amount of the dispute must not exceed €5,000 (for individuals).

b. How to Refer to the Mediator?

  • Online: Via the Insurance Mediation website.
  • By post: Send a letter explaining your dispute, accompanied by copies of your contract, the denial letter, and your challenge.

c. Processing Time

The mediator generally issues an opinion within 3 to 6 months. This opinion is not binding on the insurer, but it is often followed. If the mediator rules in your favour, the insurer has every interest in compensating you to avoid litigation.

6. Initiate Legal Action

If mediation fails, you may initiate legal proceedings to assert your rights. Here are the possible options:

a. Refer the Matter to the Judicial Court

For disputes exceeding €10,000, you must refer the matter to the Judicial Court. For smaller amounts, the Local Court (or the Judicial Court depending on the case) has jurisdiction.

  • Deadline to act: You generally have 2 years from the date of the refusal to initiate legal action (this period may vary depending on the contract).
  • Cost: Legal fees (lawyer, bailiff) can be high. If your income is modest, you may apply for legal aid.
  • Processing time: A trial may take several months, or even years.

b. Engage a Specialist Solicitor

An insurance law solicitor can help you:

  • Analyse the strength of your case.
  • Draft legal submissions for the court.
  • Negotiate with the insurer to reach a settlement before trial.

c. Claim Damages

If the insurer’s refusal is deemed abusive, you may claim damages for the harm suffered (e.g., if the refusal worsened your financial situation).

Tips to Maximise Your Chances of Success

Challenging a denial of compensation can be lengthy and complex. Here are some tips to improve your chances:

1. Act Quickly

The deadlines for challenging a refusal are often short. The longer you wait, the harder it will be to gather evidence or access appropriate remedies.

2. Document Everything

Keep all evidence related to your claim and your exchanges with the insurer:

  • Photos or videos of the damage.
  • Quotes, invoices, expert reports.
  • Copies of your reports and the insurer’s responses.
  • Acknowledgment of receipt for your registered mail.

3. Be Precise and Factual

In your communications with the insurer, avoid emotional arguments. Focus on facts and evidence to support your challenge.

4. Seek Assistance

If the dispute is complex or the amounts involved are significant, do not hesitate to seek help from:

  • A consumer association (such as UFC-Que Choisir or CLCV).
  • A specialist solicitor in insurance law.
  • A mediator or conciliator.

5. Consider an Amicable Settlement

Litigation can be lengthy and costly. If the insurer proposes a settlement (even partial), consider it seriously. A bad settlement is sometimes better than a good lawsuit.

Frequently Asked Questions

1. Can my insurer refuse to compensate me without reason?

No. Under French law, the insurer is obligated to provide a written justification for their refusal. If the refusal is not justified, you may challenge it by requesting a detailed explanation.

2. What is the deadline to challenge a denial of compensation?

You generally have 2 years from the date of the refusal to initiate legal action. This period may vary depending on the contract, so check the clauses of your insurance.

3. Can I challenge a refusal if I have signed a settlement with the insurer?

If you have signed a settlement (such as a compensation protocol), you can no longer challenge it, except in cases of defect of consent (error, fraud, or duress). In such cases, you must prove that the insurer deceived or coerced you into signing.

4. How much does an independent expert cost?

The cost of an independent expert varies depending on the complexity of the claim and the expert chosen. Expect to pay between €200 and €1,000 for a simple expert report. Some experts offer fixed rates.

5. What should I do if the mediator sides with the insurer?

If the mediator issues an unfavourable opinion, you may still initiate legal action. The mediator’s opinion is not binding, but it may influence the judge. Consult a solicitor to assess your chances of success.


Challenging a denial of compensation by your insurer may seem daunting, but by following these steps, you maximise your chances of success. Remember: your insurer has legal obligations, and you have rights. If the refusal seems unjustified, do not give up. Act methodically, document everything, and do not hesitate to seek professional assistance.
